fortran_domain doesn't handle arguments declared as "double precision" correctly.

[sradanov]

An argument of a subroutine declared as
DOUBLE PRECISION,DIMENSION(:,:),INTENT(IN):: MYVAR
appears as

• precision [double]
  in the documentation, instead of something like
• myvar(,)[double precision, in]
  I suppose something is going wrong around this line:
  re_fieldname_match = re.compile( r'(?P<type>\b\w+\b(?P<kind>\s*\(.*\))?)?\s*(?P<name>\b\w+\b)\s*(?P<shape>\(.*\))?\s*(?P<sattrs>\[.+\])?').match
  since everything seems to be fine until the scan_fieldarg method of the FortranDocFieldTransformer class
  where
  print(fieldname)
  gives
  double precision myvar(,) [in]
  but the method returns
  precision None double None
  instead of
  myvar (,) double precision in

An idea of how to change re_fieldname_match:
Option 1 : let double precision be a special case of type : re_fieldname_match = re.compile(r'(?P<type>\b(?:double precision|\w+)\b(?P<kind>\s*\(.*\))?)?\s*(?P<name>\b\w+\b)\s*(?P<shape>\(.*\))?\s*(?P<sattrs>\[.+\])?').match

Option 2 : accept only variable names without spaces but types are accepted with one space :
re_fieldname_match = re.compile(r'(?P<type>\b\w+ ?(?:\w+)?\b(?P<kind>\s*\(.*\))?)?\s*(?P<name>\b\w+\b)\s*(?P<shape>\(.*\))?\s*(?P<sattrs>\[.+\])?').match
